Introduction to Networking
Welcome to the Networking course of the IT Support Professional Certificate! In the first week of this course, we will cover the basics of computer networking. We will learn about the TCP/IP and OSI networking models and how the network layers work together. We'll also cover the basics of networking devices such as cables, hubs and switches, routers, servers and clients. We'll also explore the physical layer and data link layer of our networking model in more detail. By the end of this module, you will know how all the different layers of the network model fit together to create a network.

The Network Layer
In the second week of this course, we'll explore the network layer in more depth. We'll learn about the IP addressing scheme and how subnetting works. We'll explore how encapsulation works and how protocols such as ARP allow different layers of the network to communicate. We'll also cover the basics of routing, routing protocols, and how the Internet works. By the end of this module, you'll be able to describe the IP addressing scheme, understand how subnetting works, perform binary math to describe subnets, and understand how the Internet works.

The Transport and Application Layers
In the third week of this course, we'll explore the transport and application layers. By the end of this module, you'll be able to describe TCP ports and sockets, identify the different components of a TCP header, show the difference between connection-oriented and connectionless protocols, and explain how TCP is used to ensure data integrity.

Networking Services
In the fourth week of this course, we'll explore networking services. We'll learn about why we need DNS and how it works. We'll also show you why DHCP makes network administration a simpler task. By the end of this module, you'll be able to do describe how DNS and DHCP work, how NAT technologies help keep networks secure, and how VPNs and proxies help users connect and stay secured.

A lot of information, but i feel like i fully understand core networking concepts. A lot of this info has helped me comprehend what will be required for me when I take my Network + certification exam.
par TSAug 5, 2019
This was a very fun course! I really enjoyed the style and pace of the information given. A lot of technical information was given while the course made it easy to take in and comprehend the material!
par AMFeb 18, 2020
Apply yourself to these terms and concepts and you will gain knowledge that is presented in a very understandable way. Watch and rewatch the course videos and I promise it will all start making sense!
par TMar 22, 2018
There are a lot of acronyms and data thrown at you and you can get lost fast. Many of the classes I had to watch a few times over. It's not the easiest to understand but go slowly and you will get it.
par BCJun 23, 2018
I loved this course. When I had issues support was awesome sauce. I really enjoyed the puns this instructor used to keep you from going off in a daze. I really wish I would have found Coursera sooner.
par AAMar 25, 2020
Great course. It is great for beginners and for people that may have forgotten a thing or two. The way it was taught makes it so much better than reading man pages or something else as dry and boring.
par CAAug 6, 2018
Very dense material explained as best as it could be. I believe a few more interactive applications and more visual representations of the material would have been helpful in retaining the knowledge.
par GNSep 14, 2019
It is a very interesting course. The subject matter is very well defined and it is a nice, smooth and quick way to bring the beginners to a quite advanced level of understanding the topic. I love it.
par IIJun 11, 2018
Definitely teaches you the basic of networking that are needed to understand how it works as a whole. Would recommend anyone who is interested in learning about networking to enroll in this course.
par CFJul 26, 2019
This was a challenging but rewarding course on the basics of networking. I feel like I am walking away from this course as a more confident candidate for a role in the IT world. Thank you, Google!
par MBApr 30, 2019
I have learned so much from this course and I keep learning new things each day. I actually look forward to when I have to get back at it to learn more and push myself to do better for the future.
par MCFeb 24, 2018
Enjoyed this course But will come back again to review and strengthen my knowledge on this subject. And Thanks for all of my Instructors who has make this very understandable for students like me.
